SUBJECT: . NRC REGION 1 INTEGRATED INSPECTION REPORT NOS. 50-317/98-12 f

50-318/98-12 AND NOTICE OF VIOLATION l

t

Dear Mr. Cruse:  !

.

.

1

. This report transmits the findings of the safety inspection conducted by NRC inspectors at the j

Calvert Cliffs Nuclear Power Plant from December 13 to January 30,1999. The enclosed report i

presents the results of that inspection. At the conclusion of the inspection, these findings were -

discussed with Mr. Katz and others of your staff. l

!

Overall, the NRC has concluded that your facility was operated in a safe manner. Your conduct of  ;

activities was generally characterized by safety-conscious operations, sound engineering and l

maintenance, and careful radiological controls.  !

i

However, the NRC has determined that a violation of NRC requirements occurred. The issue was

the failure of maintenance workers to tighten bolting for the service water heat exchanger  !

strainers prior to returning the strainers after performing corrective maintenance. Tightening the  !

bolting was required by the m intenance procedure to ensure system integrity. Our inspectors  !

identified the loose bolting during a system walkdown a few days after the maintenance.

i

The NRC has concluded that information regarding the reasons for the violation, the corrective  !

action taken and planned to correct the violation and prevent recurrence is already adequately i

addressed in the enclosed report. Therefore, you are not required to respond to this letter unless ' l

the description therein does not accurately reflect your correctiva actions or your position.- In that

case, or if you choose to provide additional information, you should follow the instructions ,

specified in the enclosod notice.  !
